Lord Faringdon was used on the ex-LMS main line from Euston to Preston and Carlisle route.

Peregrine, Doncaster Works number 1877, was fitted with a Kylchap double blastpipe as from new, never having a single chimney.

In its service life it wore a variety of liveries with different numbering schemes: Garter Blue as 4903 Peregrine from its introduction, wartime black marked on tender as "NE" from 14 September 1942, it was renumbered as 34 in November 1946, garter blue with no valances as of 10 December 1947, renumbered as 60034 on 24 March 1948, renamed Lord Faringdon on 24 March 1948, painted British Railways dark blue on 4 December 1950 and finally British Railways Brunswick green on 7 August 1952.

As with all 35 of the Gresley A4 pacific steam locomotives, Lord Faringdon was fitted with streamlined valances, or side skirting, when it was built.

Lord Faringdon/Peregrine was allocated to seven depots during its career: Doncaster from new, Kings Cross Top Shed from 25 July 1942, Grantham from 5 October 1942, Kings Cross Top Shed 11 April 1948, New England 16 June 1963, St Margarets 20 October 1963 and finally Aberdeen from 17 May 1964.
